German Architect Andre Broessel believes he has a solution that can “squeeze more juice out of the sun”, even during the night hours and in low-light regions. His company Rawlemon has created a spherical sun power generator prototype called the beta.ray. His technology will combine spherical geometry principles with a dual axis tracking system, allowing […]

There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers. New research develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, rather than the narrow-band semiconductors used in traditional silicon solar cells, are best equipped for underwater use.

Wind Energy News -- ScienceDaily

Wind Energy Information. From offshore wind turbines to understanding wind turbulence, learn all about using the wind to our advantage. Also, wind testing buildings.

A new machine-learning algorithm for exploring lightweight, very stiff glass compositions can help design next-gen materials for more efficient vehicles and wind turbines. Glasses can reinforce polymers to generate composite materials that provide similar strengths as metals but with less weight.

A team has developed a less expensive water electrolysis system that works under alkaline conditions but still produces hydrogen at comparable rates to the currently used system that works under acidic conditions and requires precious metals. This advance brings down the cost of water splitting technology, offering a more viable way to store energy from solar and wind power in the form of hydrogen fuel.

A team has developed a tool to monitor changes in widely used composite materials known as fiber reinforced polymers (FRPs), which can be found in everything from aerospace and infrastructure to wind turbines. The new tool, integrated into these materials, can help measure the damage that occurs as they age.

With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life.

Much about the aerodynamic effects of larger wind farms remains poorly understood. New work looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.

Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size. Researchers have performed the first test of drag force on a thrip's wing under constant airflow in a bench-top wind tunnel and, drawing from microfabrication and nanomechanics, they created an experiment in which a thrip's wing was glued to a self-sensing microcantilever.

There is a broad argument related to the pros and cons of renewable and non-renewable sources of energy. Solar energy is a renewable source of energy that will not get exhausted over time. On the other hand, fossil fuels, including coal, petroleum, and natural gas, are non-renewable sources of energy that take millions of years…
